JavaFX 2.0 :: Freeze And Memory Consumption

I just made an application with javafx that cycles videos in a folder. I had to set the next video firing the setonendofmedia event, so they are in a cycle, but the problem is that the application loads every video at the beginning, so after a while it fills memory and crashes.Is there another way to cycle videos without pre-load them or a way to flush memory every while?

My Code :

package application;
import java.io.File;
import java.io.FilenameFilter;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
 
[Code] ....

But reading this article ( JavaFX - APIDesign ) I understand that the algorithm is obsolete. It does not quite find what is the algorithm that improves the integration of javafx and swing without using separate threads.
